8. Hilti calibration service
We recommend that the tool is checked by the Hilti
Calibration Service at regular intervals in order to verify
its reliability in accordance with standards and legal
requirements.
Use can be made of the Hilti Calibration Service at any
time, but checking at least once a year is recommended.
The Calibration Service provides confirmation that the
tool is in conformance, on the day it is tested, with the
specifications given in the operating instructions.
The tool will be re-adjusted if deviations from the man-
ufacturer's specification are found. After checking and
adjustment, a calibration sticker applied to the tool and
a calibration certificate provide written verification that
the tool operates in accordance with the manufacturer's
specification.
Calibration certificates are always required by compa-
nies certified according to ISO 900x.
Your local Hilti Center or representative will be pleased
to provide further information.
8.1 Accuracy
The accuracy of the tool in the X- or Y-directions can be
checked as described below.
8.1.1 Checking procedure

1. Set up the tool in the horizontal plane at a distance of
about 20 m (60 ft) from a wall (can also be carried
out with the tool set up on a tripod).
2. Make a mark on the wall with the aid of the laser receiver
(select medium speed of rotation).
3. Pivot the tool through 180° about its own axis (check
the same laser axis).
4. With the aid of the laser receiver, make a second mark
on the wall.
If the check has been carried out carefully, the distance
between the marks A and B should be less than 6 mm
(
7 /
32
inch; at 20 m from the wall).
⇒
In the event of a deviation in excess of this, please
return the tool to a Hilti Service Center.
9. Care and maintenance
9.1 Cleaning and drying
●
Blow dust off the lenses.
●
Do not touch the glass with your fingers.
●
Use only a clean, soft cloth for cleaning. If necessary,
slightly moisten the cloth with pure alcohol or a little
water.
-NOTE-
●
Do not use any other liquids as these may damage
the plastic parts.
●
Observe the temperature limits when storing your
equipment. This is particularly important in winter or
summer, especially if the equipment is kept inside a
vehicle (storage temperatures: –30 °C to +60 °C/
–22 °F to +140 °F).
9.2 Storage
Remove the tool from its case if it has become wet. Clean
and dry the tool, its carrying case and accessories
(at max. temperature of 40 °C/108 °F). Re-pack the equip-
ment only when it is completely dry.
Check the accuracy of the equipment before it is used
after a long period of storage or transportation.
Remove the batteries if the tool is to be stored for a long
period.
9.3 Transportation
Use either the original Hilti case or packaging of equiv-
alent quality for transporting or shipping your equip-
ment.
-CAUTION-
Always remove the batteries before shipping the tool.
